VIM<\/strong> Commands<\/h2>\n\n\n\n

Since the 1970\u2019s, Vi and its successor Vim have been included by default on many operating systems, including almost all GNU\/Linux distributions.<\/p>\n\n\n\n

Vim is free and open-source and is one of the most popular code editors. It can be downloaded on Vim official site<\/a>.<\/p>\n\n\n\n

vi (vim) line navigation FAQ: What is the vi command to move to the end of the current line? (How do I move to the end of the current line in vim?)<\/p>\n\n\n\n

Short answer: When in vi\/vim command mode, use the “$” character to move to the end of the current line.<\/p>\n\n\n\n

Movement<\/h2>\n\n\n\n
h j k l<\/strong><\/pre>\n\n\n\n
Basic movement keys. A step up from the cursor keys simply because they are already under your fingers. Most useful when prefixed with a number (e.g. if you need to move down by about 10 lines, hit \u201c10j<\/strong>\u201d instead of just holding j<\/strong> until you get there).<\/p>\n\n\n\n
b w B W<\/strong><\/pre>\n\n\n\n
Move back by token\/forward by token\/back by word\/forward by word.  (A token is a sequence of letters, digits, and underscores. For the capital letter variations, a word consists of anything that\u2019s not whitespace.) Faster than holding down a simple directional key.<\/p>\n\n\n\n
0 ^ $<\/strong><\/pre>\n\n\n\n
Jump to first column\/first non-whitespace character\/end of line, like Home and End. Faster than moving by words if you\u2019re trying to get to the opposite end of the line.<\/p>\n\n\n\n
ctrl+u ctrl+d<\/strong><\/pre>\n\n\n\n
Basically Page Up and Page Down, but moves by half a screenful and doesn\u2019t lose your cursor position.<\/p>\n\n\n\n
<line-number><\/em>G<\/strong><\/pre>\n\n\n\n
Jump directly to a specific line number. Most helpful if you also have line numbering enabled (:set number).<\/p>\n\n\n\n
H M L<\/strong><\/p>\n\n\n\n
Move to the top\/middle\/bottom of the screen (i.e. High\/Middle\/Low). A good first step in getting approximately to where you want to go.<\/p>\n\n\n\n
# *<\/strong><\/pre>\n\n\n\n
Find the previous\/next occurrence of the token under the cursor.<\/p>\n\n\n\n
n N<\/strong><\/pre>\n\n\n\n
Repeat the last find<\/em> command forward\/backward.<\/p>\n\n\n\n
\u201c<\/strong><\/pre>\n\n\n\n
(That\u2019s two back-ticks). Jump back to where you just were. This will jump back and forth between the same two locations if you keep pressing it.<\/p>\n\n\n\n
ctrl+o ctrl+i<\/strong><\/pre>\n\n\n\n
Move backward\/forward through the jump history. Useful if you have followed a chain of method calls and need to get back to where you were.<\/p>\n\n\n\n
Editing<\/h2>\n\n\n\n
In Vim, you spend most of your time in \u201cnormal\u201d mode, switching to \u201cinsert\u201d mode only when you need to add or change some text. This way, all edits become their own self-contained operations that can be repeated or chained with other operations. Most editing commands may optionally be preceded by a number in order to apply it more than once (e.g. to delete three lines, press 3dd<\/strong>).<\/p>\n\n\n\n
i a I A<\/strong><\/pre>\n\n\n\n
Enter insert mode (insert at cursor\/append after cursor\/insert at beginning of line\/append to end of line). Press Esc to exit insert mode and return to normal mode.  It\u2019s rarely useful to precede one of these commands with a number, but it can come in handy. Need a comma-separated list of eight 1s? Just hit \u201c8i1,<\/strong> <esc>\u201d then delete the trailing comma.<\/p>\n\n\n\n
o O<\/strong><\/pre>\n\n\n\n
Open new line (below the current line\/above the current line). A quick \u201co<\/strong><esc>\u201d will add a blank line below the current line, no matter where your cursor is.<\/p>\n\n\n\n
cw cW<\/strong><\/pre>\n\n\n\n
Correct the token(s)\/word(s) following the cursor. Basically combines delete and insert into one step.<\/p>\n\n\n\n
cc<\/strong><\/pre>\n\n\n\n
Correct line(s) by clearing and then entering insert mode. Starts inserting at the current indent level.<\/p>\n\n\n\n
dd<\/strong><\/pre>\n\n\n\n
Delete line(s). Quickly rearrange lines by deleting them, moving to the new location, and pasting with \u201cp<\/strong>\u201d.<\/p>\n\n\n\n
ct cf ci ca<\/strong><\/pre>\n\n\n\n
dt df di da<\/strong><\/pre>\n\n\n\n
Correct\/delete up to or including specific characters. Since there are many variations, I break it down in the section below about correcting text.<\/p>\n\n\n\n
s<\/strong><\/pre>\n\n\n\n
Delete character(s) at the cursor and then enter insert mode.  cw<\/strong> is usually faster if you want to correct an entire word, but this is useful for correcting a fixed number of characters (e.g. \u201c5s<\/strong>\u201d will correct the next five characters).<\/p>\n\n\n\n
yy<\/strong><\/pre>\n\n\n\n
Copy line(s).  The \u201cy\u201d is for \u201cyank.\u201d<\/p>\n\n\n\n
yw yW<\/strong><\/pre>\n\n\n\n
Copy token(s)\/word(s).<\/p>\n\n\n\n
p P<\/strong><\/pre>\n\n\n\n
Paste the last thing that was deleted or copied before\/after cursor (for more advanced usage, you can precede it with a register<\/em> specification, but that\u2019s a topic for another day).<\/p>\n\n\n\n
u ctrl+r<\/strong><\/pre>\n\n\n\n
Undo and redo.<\/p>\n\n\n\n
.<\/strong><\/p>\n\n\n\n
(That\u2019s a period). Repeat the previous edit command. I use this all the time<\/em>. Did you just add a line (e.g. using \u201co<\/strong>\u201d or \u201cO<\/strong>\u201d) that you need to duplicate five more times with only slight modifications?  Hit \u201c5.<\/strong>\u201d to repeat that operation, then make your modifications; no copy\/paste needed.<\/p>\n\n\n\n
Correcting Text<\/h2>\n\n\n\n
In a boring text editor, you are limited to very basic operations: highlight some text, delete it, type more text. Vim has the ability to highlight (it\u2019s called \u201cvisual\u201d mode), but I rarely use it.  It is often much faster to achieve the same thing using a few editing commands.<\/p>\n\n\n\n
I frequently need to correct some text that doesn\u2019t fall neatly onto a token or word boundary. Fortunately, operations like \u201cc<\/strong>\u201d (correct) and \u201cd<\/strong>\u201d (delete) have a number of operators that may be applied to them:<\/p>\n\n\n\n
